Key point of removal1. Apply the parking brake and chock all tires except the one to be

removed.

2. Be careful as the wheel nuts differ between the SAE type andISO type.

SAE typeThe wheel nuts on the right side of the vehicle have right-handedthreading, the left side wheel nuts have left-handed threading.

+ Changing wheel types

WARNINGUse only the same type and style wheels and mountinghardware to replace original parts. Do not use unauthorizedwheel components. Failure to do so may result in an

assembly which does not fit together properly resulting inpremature wheel or fastener failures.+ Fasteners like bolts and nuts removed from the vehicle

should be re-used in the same spot whenever possible.If not possible, new fasteners selected must match thosereplaced and obtain good metal-to-metal contact. It isimperative to identify and use only those fasteners des-ignated for use with the respective vehicle being ser-viced. Mismatched or incorrect fasteners can result invehicle damage or possible personal injury.

+ Do not attempt to mix ball seat wheels or fasteners withflange nut wheels or fasteners.

+ Do not change from aluminum wheels to steel or viceversa without changing the mounting hardware. In thecase of some flange nut assemblies, the hub must bechanged also.

NOTE+ Be careful not to damage the threads of the hub bolts with

the bolt holes in the disc wheel when removing wheel.

CTW1-001

DISASSEMBLY

Key point of disassembly1. Carefully remove the tire valve core and release all air pressure

inside the tire. If the valve is obstructed while discharging airpressure, use a thin wire to remove the foreign matter.

WARNING+ The valve sometimes freezes because of high air pres-

sure inside the tire. Do not put your face close to thevalve while discharging air pressure. Pieces of ice maysurge out, causing an injury.

NOTE+ While removing the valve core, hold it with your fingers so

that it does not pop out.

2. Drive a bead hammer between the tire bead and rim flange untilthe bead and flange separate completely.

3. Spread lubricant or soapy water on the tire bead and rim flange.

ETW003A

4. Insert the lever into the end gap of the side ring. Push it downto the point where the lever groove is visible.

CTW1004A

5. Push the other lever into the lever groove. Turn the lever overtoward the wheel center by pivoting the lever so that the sidering end surface is elevated.

CTW1004C

6. Insert the two levers between the side ring and rim alternately.Gradually pry up the levers to remove the side ring.

NOTE+ When the side ring comes off about half of the circumfer-

ence, hold remaining, yet to be removed portion of the ringwith foot.

7. Install the cap on the valve and press-fit the valve stem into thevalve hole.

CTW1006A

8. Raise the tire and gradually and push the wheel center outusing foot.

NOTE+ The wheel may suddenly come out from the tire. Be careful

not to allow the wheel to roll out.

9. Insert the lever between the bead and rim near the valve. Pushthe rim out and remove the wheel.

NOTE+ The wheel may suddenly come out from the tire. Be careful

not to allow the wheel to roll out.10. Remove the flap and then pull the tube out.

2. Drive a bead hammer between the tire bead and rim flange untilthe bead and flange separate completely.

CAUTION+ In aluminum wheels, the lever should be used carefully so

as not to damage the wheel. Never use a bead hammer.

3. Spread lubricant or soapy water on the tire bead and rim flange.

4. Insert the curved end of both levers at point 25 cm (9.8 in) fromthe valve on both sides.Insert both levers, and step on the tire opposite the valve todirect the first bead into the well.

CTW1-004

5. Hold one lever in position with your foot and lean the secondlever toward the center of the wheel.Progressively work the first bead off the rim.

WARNING+ Be careful when pulling the lever toward the center of the

wheel. The tip of the lever may slip out from the tire.

NOTE+ Take off about 1/2 the circumference. The rest comes off

easily.

CTW1-005

6. Stand the tire assembly up in the vertical position. Insert thestraight end of the lever between the tire bead and back rimflange. Lean the tire assembly slowly toward the lever.

CTW1-006

7. Push the lever to raise the wheel and insert another lever inclose vicinity to further raise the wheel by providing a rocking orbouncing action to pry the rim out of the assembly.

NOTE+ Take off about 1/3 the circumference. The rest comes off

easily.

TIRENew tireThere are many types of tire construction, tread patterns and tiresizes. It is very important to select the best one for the particularvehicle (including rims) and for the conditions it will be used in.NOTE+

Never mix the following tires on one vehicle.+ Different kinds of tires (bias, radial, etc.)+ Different sizes+ Normal tires, snow tire, snow tire with spikes+ Mount snow tires on all wheels on snowy or icy roads.Used tireCheck for abnormalities as instructed in section ‘‘MA’’. Replace iffaulty.

RIM AND DISC WHEELCheck for cracks or damage. If any of the following faults arenoticed, replace the rim and disc wheel as a unit.

Cracked bead seatIf left unheeded, the cracked area will increase with operation,resulting in damage to the tire. This is very dangerous.

Deformed flangeA deformed flange results from heating due to partial movement ofthe tire or trapped foreign matter.

Corroded bead seatExcessive corrosion reduces the thickness of the seat, resulting ina decrease in strength and safety.

Damaged seating surface of nutsFatigue or cracks will result with operation if the nut is not tightenedto the specified torque.

Cracks on designed holesThis is due to overloading. If left unheeded, the cracked area willenlarge resulting in breakage.

REASSEMBLY

Key point of reassembly1. To prevent friction between the tire inside and tube, and the

tube and flap, coat each part with talc powder.

ETW007A

2. Blow a small amount of air into the tube and insert the tube intothe tire.

NOTE+ Be sure to blow air with the valve core installed.

ETW008A

3. Insert the valve stem into the valve hole in the flap. Sequentiallyinsert the flap uniformly.

NOTE+ Be careful not to allow the upper and lower ends of the flap

to bend inside the tire.

ETW009A

4. Place the wheel on a level surface and insert the valve steminto the valve hole.

ETW010A

5. Fit the tire in the wheel by slowly sliding the tire around thewheel. Then, rotate the wheel so that the valve is located in thecenter of the rim hole.

6. Press-fit the side ring into the rim groove.NOTE+ Locate the end gap of the side ring 90°from the valve so it

is evenly spaced between the disc ornamental holes.

INSTALLATION

Key point of installation+ Procedures for mounting tires differ between the SAE type and

ISO type. When installing tires, be sure to observe precautionsfor each tire.

ETW020A

ETW031A

SAE type1. Clean the wheel mounting surfaces with a wire brush and clean

waste cloth. Dirty mounting surfaces may cause the wheel nutsto loosen.

2. Apply a coat of engine or gear oil to the threaded portions of thehub bolts and wheel nuts only. Do not use molybdenum greasefor this purpose.

3. The wheel nuts on the right side of the vehicle have right-handed threading; the left side wheel nuts have left-handedthreading.

4. Tighten the wheel nuts in the sequence shown in the figure littleby little to the specified torque.

: 412 - 481 N·m {42 - 49 kgf z m, 304 - 354 ft z lbf}NOTE+ Do not tighten the wheel nuts excessively.+ After removing only the rear outer wheel, retighten the

inner wheel nuts to the specified torque setting.

ISO type1. The left and right wheel nuts have the same right-hand thread

designs.2. Clean the wheel mounting surfaces with a wire brush and a

clean waste cloth. Dirty mounting surfaces may cause thewheel nuts to loosen.

DK-105E

3. Remove any foreign material from the tapered portion betweenthe wheel nuts and washers using compressed air so that thewheel nuts and washers rotate smoothly. If they do not rotatesmoothly, replace them with new ones.
